Figure 1a below shows the measured Color Gamuts for the 12X along with the Standard sRGB / Rec.709 and DCI-P3 Color Gamuts. The outermost white curve is the limits of human color vision - the horseshoe is the pure spectral colors and the diagonal is the Line of Purples. A given display can only reproduce the colors that lie inside of the triangle formed by its Primary Colors.
Selectable Color Modes
The 12X provides 3 user selectable Color Modes:
The
Original
Mode, which provides the most Accurate Colors with Automatic Color Management
for ICC Content.
The
Vivid
Mode, which has more Vibrant Colors and Contrast.
The
Saturated
Mode, which has the Native Wide Color Gamut of the OLED display.
Accurate White Points
The dots in the center are the measured color of White for each of the
Color Gamuts along with the D65 Standard White,
which is marked as a white circle.
To deliver accurate image colors the display must match both
the Standard Color Gamut and the Standard Color of White.
Accurate Color Gamuts
The Standard Color Gamuts are marked with Black and Gray dots in
Figure 1a
below.
The Original Mode DCI-P3 Color Gamut is an accurate match
to the DCI-P3 Standard Color Gamut
that is used to produce the new 4K UHD TV content.
The Original Mode sRGB Color Gamut is an accurate match
to the sRGB / Rec.709 Standard Color Gamut
that is used for most existing consumer content.
Both of the 12X Original Mode Color Gamuts are a close match to the Standard Gamuts.

measurements for each of the Color Gamuts.
The Reduction in the Color Gamut with Ambient Light
Figure 1a
above shows the Color Gamuts in 0 lux Ambient Light,
which is absolute darkness.
Figure 1b
below shows the reduction in the Color Gamut with increasing Ambient Light
for the
Saturated
and
Original
Modes.
For the sRGB and DCI-P3 Original Modes:
At 500 lux, which corresponds to typical office lighting, the on-screen
Color Gamut is reduced to 88-89%.
At 1,000 lux, which corresponds to very bright indoor lighting or
outdoor daylight with an overcast sky,
the on-screen Color Gamut has fallen to 78-79%,
and at 2,000 lux, which corresponds to typical outdoor daylight in shade,
the on-screen Color Gamut has fallen to 64-66%.
